Description
Technical field
The utility model belongs to power shovel band-type brake technical field more particularly to a kind of power shovel locking system brake block abrasion alarm dress
It sets.
Background technique
In mining production, power shovel system is mainly responsible for mineral aggregate, the excavation of rock, extraction work, work
Reliability and safety directly affect the normal production and economic benefit in mine.The locking system of power shovel is power shovel traveling, returns
How the key component of rotation protection reliably detects the brake block abrasion situation of locking system, is the key that realize power shovel safe operation
Technology.
Electric dipper slewing and traveling locking system are without brake block abrasion situation automatic detection means at present, only by operation, inspection
It repairs personnel to be judged according to artificial experience, error is larger.In actual operation, since site environment is severe, dust is larger, lock
In the case that watt abrasion condition cannot be grasped in time, the case where overground, few mill just carries out inappropriate replacement generation that there is brake shoes,
It is unfavorable for the safe operation of power shovel and the raising of economic benefit.
Summary of the invention
It can be realized the object of the present invention is to provide one kind and power shovel locking system brake block abrasion situation be measured in real time
And alarm, long service life, strong interference immunity, the good power shovel locking system brake block abrasion alarm of the reliability and stability of measurement
Device,
The utility model is achieved through the following technical solutions.
A kind of power shovel locking system brake block abrasion warning device of the utility model, including by brake wheel, brake shoe, bracket and company
The power shovel locking system of bar composition, which is characterized in that further include linear displacement transducer and monitoring system, the straight-line displacement
Sensor is mounted on the end of connecting rod, and the output end of the linear displacement transducer is electrically connected with monitoring system,
The monitoring system includes transmitter, Analog input mModule, programmable controller, communication module, display
Screen, switching value output module and alarm, the linear displacement transducer are defeated by transmitter and Analog input mModule
It is connected after inbound port with programmable controller, after programming sequence controller receives the processing of linear displacement transducer data operation, leads to
It crosses communication module and display screen to show the status parameter values of power shovel locking system brake block abrasion on a display screen, the alarm
Device and the outlet end of switching value output module be connected.
The beneficial effects of the utility model are: using advanced linear displacement transducer, in conjunction with reliable programmable control
Device technology processed carries out online comprehensive monitoring and judgement in real time to power shovel locking system brake block abrasion situation, and working condition carries out simultaneously
It is shown and is alarmed.And then effective control of the realization to power shovel locking system, the working efficiency of power shovel is provided, extends and uses the longevity
Life, facilitates maintenance, increases economic efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model power shovel locking system brake block abrasion warning device.
Fig. 2 is power shovel locking system brake block abrasion warning device monitoring system connection block diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of power shovel locking system brake block abrasion warning device of the utility model, including by brake wheel 2, lock
Watt 1, the power shovel locking system that bracket and connecting rod 3 form, which is characterized in that further include linear displacement transducer 4 and monitoring system
5, the linear displacement transducer 4 is mounted on the end of connecting rod 3, the output end of the linear displacement transducer 4 and monitoring
System is connected,
As shown in Fig. 2, the monitoring system of the utility model includes transmitter, Analog input mModule, may be programmed
Sequence controller, communication module, display screen, switching value output module and alarm, the linear displacement transducer pass through pick-up
It is connected after the input port of device and Analog input mModule with programmable controller, programming sequence controller receives straight-line displacement and passes
After the processing of sensor data operation, the status parameter values of power shovel locking system brake block abrasion are shown by communication module and display screen
On a display screen, the alarm and the outlet end of switching value output module be connected.
Since the utility model linear displacement transducer 4 is mounted on the end of connecting rod 3, power shovel band-type brake system can be acquired in real time
System brake block abrasion situation simultaneously passes data on programmable controller, and programming sequence controller receives linear displacement transducer data
After calculation process, the status parameter values of power shovel locking system brake block abrasion are shown in display screen by communication module and display screen
On, the alarm and the outlet end of switching value output module be connected.
The utility model is judged using the linear displacement transducer of high reliability instead of original artificial experience, and control is improved
The global reliability of system, the service life is long, strong interference immunity, guarantees the work of power shovel locking system reliably and with long-term.
